Reversing Your Ceiling Fan Adds Comfort in the Warmer MonthsHaving a ceiling fan in addition to an air conditioning system makes your home much more comfortable in warmer months because the fan helps circulate the cool air. However, you might have your fan set in a way that prevents you from getting the full benefit of the fan. Ceiling fans have the ability to rotate in either direction, and reversing your ceiling fan can make a huge difference in how cool you feel during summer.

If you look at your ceiling fan’s housing — turn the fan off, first — you’ll see a small switch. Moving this switch will reverse the direction in which the fan rotates, and that affects how much air is forced downward when the fan is on because the angled blades will be pulling or pushing air up or down.

When ceiling fan blades are rotating in a clockwise direction, so that the air hits the lowered edges of the blades first, the air is sucked up toward the ceiling. Remember that warm air rises, so in winter, the air from your heater actually heads up toward the ceiling. The air pulled up by the clockwise fan blades displaces the warm air already up there, and that warm air is then pushed down into the general space in the room. When the fan blades rotate in a counter-clockwise direction, however, the air is pushed down. This creates a chilling effect on you, much like a cool breeze would outside.

So whenever the weather is warm enough to require some cooling, you want those blades rotating in a counter-clockwise direction. If you’ve been using the fan and not really feeling any benefit from it, reversing your ceiling fan is the first step to take. The direction in which the blades are rotating is the most likely culprit.
